Anything by H. P. Lovecraft. Though technically they aren't 'books' in the sense that they aren't novels. But his short stories have a way of connecting with each other into a larger universe. I often refer to Lovecraft as the J. R. R. Tolkien of horror. If you really want a novel, however, the closest would be "At the Mountains of Madness" which is the only short novel he ever wrote. If you haven't checked him out already, now would be a good time.

Just a big thankyou to everyone who gave me some great movie additions to my Best Horror movie hubs!!! The Killer Creatures, Deadly Virus, and When Animals Attack are getting better by the day. Please keep the helpful...
